Problems solved by technology

Its features solve the shortcomings of traditional LED display screens, such as the influence of visual range and poor heat dissipation effect due to the fact that the display and light-emitting pixels are arranged on an opaque plane structure, but because each unit board of this invention is fixed on the peripheral frame, it increases The weight of the display screen, the installation method is not flexible enough

Embodiment Construction

[0020] figure 1 It shows the first embodiment of the air-permeable LED screen of the present invention. Several PCB circuit boards 4 are connected through a power supply positive line 1, a signal control line 2, and a negative line 3, and each PCB circuit board 4 is equipped with There is an LED light-emitting unit 6, which includes at least one light-emitting diode; a single-wire transmission control chip 5, which controls the LED light-emitting unit 6 to emit light; a power supply positive line 1 and a power supply negative line 3, which are connected to the LED single-wire The transmission control chip 5 is connected; a signal control line 2, input control signals to the LED single-line transmission control chip 5, to control the LED light emitting unit 6 to emit light. A signal control line 2 and a power supply positive line 1 are merged side by side to form a line. A transparent space is formed between the space and the connecting lines of two adjacent PCB circuit boards...

Abstract

The invention discloses a hollow LED halftone screen, which consists of a plurality of unit plates; each unit plate comprises a plurality of PCB circuit boards; each PCB circuit board comprises an LED light-emitting unit, a single wire transmission control chip, a positive source line, a negative source line and a signal control line; and the plurality of PCB circuit boards in each unit plate areconnected at any angle into a net shape through the positive source line, the negative source line and the signal control line, and a penetrating blank space is formed between two adjacent PCB circuit boards and two adjacent PCB circuit board trunks. The hollow LED halftone screen has the advantages of simple lines, stable control signals, steady screen body, flexible mounting mode, low production cost and the like, and can be mounted by adopting modes such as beam type, single sling type, double sling type and multi-sling type.

Description

technical field [0001] The invention relates to an LED display screen, in particular to a transparent LED screen. technical background [0002] LED is widely valued for its high luminous efficiency, long service life, safety, reliability, environmental protection and energy saving. The light-emitting diodes have primary colors such as red, blue, and green. The display screen can be composed of LED light-emitting points of one primary color to form pixels. Pixels can also be composed of LED light-emitting points of any two or three primary colors, and then the brightness of each primary color in each pixel is controlled by a special drive circuit and control system, thereby displaying colorful videos, pictures, texts, etc. Screen. As an important means of information dissemination, LED display has become a symbol of urban information modernization. With the continuous progress of social economy and the continuous improvement of LED display technology, people's understanding o...
